I would use a DOM parser and XPath to select the content of that span tag. Like this:

$url = 'https://www.google.com/finance?q=USDZAR';

$doc = new DOMDocument();
@$doc->loadHTMLFile($url);

$selector = new DOMXPath($doc);
$span = $selector->query('//span[@class="bld"]')->item(0);

var_dump($span->nodeValue);
